DINING-TABLE.

Specification of Letters Patent. Patented Feb. 25, 191%.

Application filed. December 30, 1916. Serial No. 139,858.

To all to 700m it may concern:

Be it known that I, FRANK DU Bors JA UETTE, a citizen of the UnitedStates, residing at Pasadena, in the county of Los Angeles and State ofCalifornia, have invented certain new and useful Improvements inDining-Tables, of which the following is a specification.

This invention relates to dining tables and more particularly to diningtables of the self-serving type and has for one of its objects toprovide novel means for rotating the inner or movable section of thetable top which means will be so constructed as to permit of ready andconvenient operation of the said section of the-table top when desired.

Another aim of the invention is to pro vide in a table of this class acentral fan shaft which may be continuously rotated or held stationaryas desired and the operation of which will be independent of theoperation of the central or movable section of In the drawings thenumeral 1 indicates 4 in general the fixed sectionof the table top whichsection may be annular in form, as

shown in the present drawings, or may be rectangular or in fact'of anydesired shape and size and this section of the top is rigidly supportedupon the upper ends of arms 2 which extend upwardly and outwardly from acentral pedestal 3 supported by the usual feet 4, this pedestal beinghollow so as to receive the operating shafts for the movable table topsection and the fan, as will be presently fully described. The table topsection 1 being annular in form, defines an opening 5 located centrallyof the top of the table and within this opening is rotatably mounted theinner or movable section of the top which is indicated in general by thenumeral 6 and which is supported by arms or brackets 7 radiating from acentral hub 8 which is keyed or otherwise secured as at 9 to the upperend of a sleeve shaft 10 through the medium of which the-said section ofthe top is to be rotated. lVithin the pedestal 3 is arranged a tubularhousing 11 terminating at its upper end in a substantially annularhorizontally disposed head 12 having an upstanding peripheral flange13.. This head is providedin its upper face with a ball race 14receiving bearing balls 15 and the lower end of the hub 8 of the centralor movable section of the table top is secured in any suitable man norupon a bearing plate 16 which is circular in form and is provided in itsunderside with a ball race 17 also receiving the hearing balls 15, thesleeve shaft 10 extending axially and rotatably through the tubularhousing 11 in the manner clearly shown in Figs. 2 and 4 of the drawings.It will now be apparent that the entire weight of the inner or rotatablesection of the table top is borne by the pedestal 3 and that the saidsection of the top may have rotary motion attended with minimumfriction. Upward displacement of the section 6 of the table top isprevented through the provision of an annular cap plate 18 which issecured upon the upper edge of the upstanding flange 13 of the head 12and it is preferable that hearing balls 19 be arranged within ball racesformed in the upper side of the bearing plate 16 and the underside ofthe annular cap plate 18, the cap plate surrounding the lower portion ofthe hub 8 and the bearing plate projecting at its periphery beyond theircumferential surface of the said lower portion of the hub, as clearlyshown in Fig. 2 of the drawings.

In order that any liquid spilled upon the surface of the inner orrotatable section 6 of the top may be prevented from flowlng to theoperating mechanism or on to the means is provided upon the underside ofthe fixed section of the top at some point in the circumference thereoffor cooperation. with this flange whereby the rotary motion of the topsection 6 may be controlled. In the present structure, bearings 24 aresecured upon the underside of the fixed section 1 in radial alinementwith relation to the table top and a rod 25 is rotatably mounted inthese bearings and is threaded near its outer end, as at 26, wherebyupon rotation the rod will be fed inwardly or outwardly depending uponthe direction of such movement. In order that the rod may be rotatedfinger knob 27 is fixed upon its outer end. The rod is provider at itsinner end with a socket 28 within which is fitted a friction plug 29which may be of rubber or of'any other suitable material and which, uponinward movement of the rod is designed to be brought into frictionalengagement with the outer surface of the brake flange 23, whereby tohold the inner or rotatable section of the top against movement,it'being understood that by backwardly rotating the rod the same will beadjusted outwardly so as to bring the friction plug out ofcontact with.the [brake flange, thereby oer-mitting the inner section of the top torotate to the desired position.

Any suitable device may be employed for rotating the central section ofthe table top, but themeans here illustrated is in the nature ofa springmotor 30 which is housed within a casing 31 supported beside thepedestal 3 of the table. The winding shaft of this motor is indicated bythe numeral 32 and has fixed upon it a sprocket 33 about which and asprocket 34 is trained a spocket chain 35. The sprocket 34 is fixed upona shaft 36 provided at its outer end with a crank handle 37 and it willbe understood that by rotating this handle the spring of the motor maybe placed under tension. The numeral 38" indicates an exteriorly squaredsleeve shaft which is driven by the motor 30 and which constitutes oneof the two power shafts of the motor, the said shaft surrounding a shaft39 which is designed to be continuously rotated by the motor mechanism.Mounted upon the shaft 38 is a beveled gear 40 which meshes with asimilar gear 41 rotatably mounted beneath the casing 31. The gear 41. isfixed with relation to a sprocket gear 42'about which is trained asprocket chain 43 and'this chain passes also about a sprocket gear 44fixed upon the lower end ofthe shaft 10. While any suitable type ofmotor may be employed andwhile the specifi'c construction thereof is notherein illustrated asit constitutes no part of the present mvention, themotor mechanism is such that while the shaft 39 is continuously rotatedthe motor mechanism at all times tends to rotate the shaft 38, thisshaft may be held against rotation, without, however, interfering withrotation of the shaft 39. Conse quently, while there is at all times atendency for the gear 40 to rotate and impart rotary motion to the gear41 and thence to the shaft 10, so long as the brake device heretoforedescribed is in active cooperation with the brake flange 23, the centralor rotatable section of the table top will be held stationary. However,as before stated, when the rod 25 is rotated backwardly the brake devicewill be rendered inactive and the said rotatable section of the tabletop will be turned. or rotated through the gearing just described. Thenumeral 45 indicates a fan shaft provided with a squared upper end 46 towhich is removably fitted the lower end of a shaft section 47 carryingfan blades 43 at their upper end. At its lower end the fan shaft 45 isprovided with a sprocket gear 49 about which is passed a sprocket chain50 and this chain also passes about a sprocket gear 51 which is fixedwith respect to or formed integrally with a beveled gear 52 mountedbeneath the casing 31 and beneath the gears 41 and 42. The gear 52 is inmesh with a beveled gear 53 which is loosely mounted upon the shaft 39but is designed to be clutched for rotation with the said shaft througha clutch device which will now be described. The numeral 54 indicates across piece arranged within the casing 31 and through which the saidshaft 39 ex tends, as clearly shown in Fig. 4 of the drawings. Eitherintegral with this cross piece or fixed thereto in any suitable mannerand concentric with relation to the shaft 39 and surrounding the same isa disk 55 formed in its outwardly presented face with diametricallyoppositely located sockets 56, the bottom or inner walls of which areinclined for a purpose to be presently made clear. A collar 57 ispreferably fixed upon the shaft 39 and by coiiperation with theoutwardly presented face of the disk 55 provents outward movement of thedisk along the said shaft. The numeral 58 indicates a disk which isrotatably mounted upon the shaft 39 and which is provided with lugs 59having inclined faces 60, these lugs seating in one position of theparts in the sockets 56, as shown in Fig. 4 of the drawings. A rod 61 ispivoted at its lower end to the periphery of the disk 58 and at itsupper end to a lever 62 pivotally mounted as at (33 upon the top of thecasing 31 and provided with a handle portion 64 which may be depressedfor the purpose of rotating the disk 58 causing the inclined faces ofthe lugs 59 to ride against the inner or bottom walls of the sockets 56,thereby causing movement of the disk 58 bodily away from the disk 55 andlongitudinally of the shaft 39. Also fixedupon the shaft 39 outwardly ofthe disk 58' is-a collar 65'l1aving radial arms 66 provided with bearingportions 67 at their outer ends. These portions slidably receive thestems 68 of clutch shoes 69 designed for cooperation with the inner faceof an annular clutch flange 70 formed upon the inwardly presented faceof the gear Links 71 are pivoted at their outer ends as at 72 to theinner ends of the stems 68 and at their inner ends as at 73 to a collar74- slidably and yet nonrotatably held upon the shaft 39 as for exampleby being splined thereto, as indicated at 75. When it is desired torender the fan active the lever 62 is rocked so as to pull upwardly uponthe rod 61 and in this movement of the rod the disk 58 will be rotatedbackwardly so as to into and out of mesh with the gear 41, the

said gear 40 has associated therewith a grooved collar 76 with whichcooperates a yoke 7 7 at the lower end of a shifting lever 78 which ispivotally mounted as at 7 9 within the casing and which extends at itsupper end through a slot 80 at the top of the casing and is providedwith a hand grip 81.
